No, he probably didn't get the latest DME update. The recall notice was sent out to update the DME. Without the update, you will not get check engine lights even without cats.

Once the update is done (without your knowledge at an oil change?), you will throw the CEL.

Federal law requires them to implement emissions fixes, so I doubt you can convince your dealer to violate federal law for you and NOT update the DME.

NYCGarbagePrince · 11-02-2007, 02:48 PM

your right the update did do that. However I have had CEL's for 4 or 5 months? haven't had BMW do my oil changes. In this case there is only one reason for his lack of CELs. He knows it and has spoke on it. But for some reason chooses not to say so on a regular basis.

Hopefully he lives in the Atlanta area and has access to and like to share vehicle specific tools.

A little OT, but we'll need to hit the dyno again soon because my UR catted DPs are on their way...know any shop good enough to install them? Also, I understand your V2 is on its way, so pls let me know when you get it installed so we can go for a drive!

Definitely...

As for a shop, I would not be able to suggest anyone as I always do these things myself. So, if you wanted to make a afternoon of it and drive up to Woodstock, I would be glad to swap them for you.

Oh man, you're on!! I'll bring the beer and food. What kind of beer do you like?

I am easy, Miller Light or Bud Light. I am more of a quantity versus quality person.

Let me know when they arrive and we will schedule a Saturday. In reviewing the information in the install, I see they will be easier than the B5 S5 downpipes which took me about 5 hours. I suspect these will take 3 - 4 hours. It is especially nice since they are on the same side and a single band clamp versus three bolts (rusted) each.

I would especially be interested in us running out on I-575 for some pulls afterwards. It would be a V1.47 with DP's against a V2.0.1.

Cruise at 45 mph or so for about 5-10 minutes at lite throttle a couple of times and the catless pipe should throw a code.

Any of the various O2 simulators on the market should work; the 2 sensors up by the engine are for the a/f; the ones on the other side of the cats are the same- the ODB-II reads before cat and after cat; if the voltage isn't different it'll throw a light. The sensor simulators just modulate the voltage for the rear O2's at a different level so the ECU thinks everything is great.

Former_Boosted_IS · 11-05-2007, 07:32 AM

o2 sims are so common... why wouldn't these manufactorers have them on these pipes? I am sorry, but CEL's on a $45k car is downright embarrassing.

Hallandale E92 · 11-15-2007, 07:45 PM

Hey guys had my DP's on for a week now and i got a cel for one morning drive but other than that it hasnt been on....?

DarrinYuan · 11-15-2007, 09:33 PM

Hallandale E92 · 11-15-2007, 10:02 PM

Why is your gas mileage so bad? Is your car going into LIMP and running fat?

DarrinYuan · 11-16-2007, 11:18 PM

I think I have to get AA custom map for the catless dp's.

Walked U · 11-16-2007, 11:22 PM

Ooops i think i pressed yes. I meant no cel. hahaha

ADHD · 11-17-2007, 01:01 PM

Catless Coated DP's been installed for a bit over a week know!! NO CEL's!!!

Terry335 · 11-17-2007, 01:20 PM

Hey guys, I will be making simms soon for those that experience the no cat CEL. Traditional simms won't work as the rear o2 sensor voltage doesn't switch around .5mv, but worry not we've got a solid design on the table.

Terry, that is good to hear and I am sure you will have a market here for them. The sooner the better as I suspect a ton of people will be installing the Riss very soon.

DarrinYuan · 11-19-2007, 02:56 PM

I think those are same between Riss dp and Ur dp,Riss dp just more expensive.
